如何解决 Android 应用程序在发布构建类型中崩溃但在调试构建类型中有效

Question

Android 应用在使用 Release Type 构建时在手机中崩溃，但在使用 debug 构建类型构建或在发布模式下启用调试时工作正常。

由于抽象类之一，Logcat 错误显示验证错误

应用程序中没有 proguard 文件。我试过添加 build.gradle 中的“useProguard false”，但无济于事

apply plugin: 'com.android.application'

android {
    useLibrary 'org.apache.http.legacy'
    compileSdkVersion 28

    defaultConfig {
        applicationId "com.newgen.mcap.srei"
        minSdkVersion 21
        targetSdkVersion 28
    }

    buildTypes {
        release {
            minifyEnabled false

        }
    }
    lintOptions {
        checkReleaseBuilds false
        disable "ResourceType"
    }

}

dependencies {
    compile 'com.android.support:support-v4:23.4.0'
    compile files('libs/com.antlersoft.android.db_0.1.6.jar')
    compile files('libs/commons-lang3-3.1.jar')
    compile files('libs/dmsapi.jar')
    compile files('libs/ImgAndro.jar')
    compile files('libs/NGSecurity.jar')
}

这里出现Logcat错误：

我的问题与Link 不重复 因为崩溃是由于构建类型而不是由于 android api 级别。我已经通过在构建 apk 之前删除构建和发布文件夹来尝试接受的答案。

Answer 1

它与调试/发布版本无关。您应该在

中处理异常

com.newgen.mcap.client.util.NGCaptureSingleton.getDefaultCustomHelperForName
(NGCaptureSingleton.java:109)

Answer 2

步骤 1：打开 Android Studio 设置并转到构建、执行、部署 -> Gradle 复制 Gradle 服务目录路径 在我的情况下是 C:/Users/bhanu.sharma/.gradle

第 2 步：打开文件资源管理器并粘贴 Gradle 服务目录路径 如果文件 gradle.properties 不存在，请在此处添加

第 3 步：打开 Android Studio 并将项目类型更改为 Android，您将看到 gradle.properties 文件在这里

第 4 步：在 gradle.properties 文件中添加 android.enableD8=false 行。

第 5 步：清理并构建签名的 apk。
